COMPRESSOR.

SPECIFICATION forming part of Letters Patent No. 376,598, dated January 17, 1888. n

Application filed January 21, 1887.

.To l@ZZ whom, it may concern.-

Be it known that'l, HARRY JONES, of Lancaster, in the county of Goos and State of New Hampshire, have invented a new and Improved Compressor, of which the following is a full, clear, and exact description.

This invention relates to anovel form of machine adapted for use in compressing dry or nearly dry powdered substances into solid form, the machine being applicable for use in many branches of the mechanic arts, but being more especially designed for'the use of druggists in the making of what are commonly known as compressed tablets.7 l

The invention consists,essentially,of an automatic measuring mechanism and an automatic compressing mechanism,the two mechanisms being combined in a manner to be hereinafter more fully described, and specifically pointed out in the claims. 1

Reference is to be'had to the' accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side view of my compressingmachine, the supporting box or bed and a .portionrof the revolving disk being shown in v Y 6, 7, and 8 are detail views illustrating the va- -rious positions assumed by the compressingplungers as the disk revolves. Fig. 9 isasectional plan View taken on line y y. of Fig. 1, the parts, however, being shown in a different position from that in which they are illustrated in Fig. l. Fig. 1()V is a View of the cam-ring and the adjustable camsections employed in connection with the lower compressorplungers; and Fig. l1 is a view of a construction wherein a number of sets of compressor-plungers are employed instead of a single set of such plungers, as in the case of theconstruction illustrated in the first four figures of the drawings.

In constructing such an apparatus as the one r illustrated in the drawings above referred to I provide a base-.plateor case, 10, which is formed with a vertical tube, 11, within which there is mounted ashaft, 12, to which there isv Serial No. 225,023. (No model.)

keyed a sleeve, 13', that is made integral with a disk, 14, and with arms 15, verticallyslotted tubes 16 and `17 being formed at the extending endsof the arms 15.

To the'lower end of the shaft l2 there is secured a bevel-gear, 18, that is engaged by a corresponding gear, 19, which iscarried by a short horizontal shaft, 20, said shaft being in turn provided with a pulley, 21, over which there is passed a driving belt or chain,22, that runs in engagement with a second pulley, 23, of the same diameter as the pulley 2l, which said pulley 23 is carried by the main powershaft 24, said shaft being supported in bearings carried by a double standard, 25, the shaft 24'being driven by a belt which runs in en gagement with a pulley, 26,` that is carried by the' shaft.

Two vertical standards, 30, are secured to the case or bed-plate' 10, the upper ends of4 being shown at 3i, the two sections being 2, as probably best shown in 2 and 9, these bends being made at a point so that as the disk 14 is revolved an aperture, 4, that is formed in the disk will pass directly beneath the bends. The purpose of this formation willl be presently explained. Vithin the aperture 4. of the disk 1i there is arranged a bushing, 5, said bushing being preferably made of hardened steel.

Within the tubes 1G and 17 there are a1- ranged compressing-plungers 38 and 39,which said plungers are held against turning within the tubes by outwardly-extending projections or'pins 6,the points of these plungers registering with the central bore or aperture of the FSO IOO

bushing 5, so that the plungers may be advanced to enter said bore or aperture.

In connection with the lower plunger I arrange a ring or way, 40, that is broken away in two places, adjustable cam-blocks 4I and 41 being arranged at the points where the ring is so broken away, the cam-blocks being supported by coiled springs 42, that are coiled about threaded shauks 42, said shanks being engaged by nut-s 43, this construction being best shown in Figs. 1 and 3. rIhe upper compressor-plunger is normally upheld above the feed-box by the engagement of its pin 6 with a ring, 44, that is supported by the standards 30,said ring being broken away,as best shown at a in Fig. 2, one end of the ring being bent down to form a camface, b.

In connection with the parts described I arrange a hammer-,45,that is carried by the long arm of a lever,46,said lever being mounted between the arms of the double standard 25. The short arm of the lever 46, which extends downward between the arms of the standard 25, carries a friction-roller, 47, which is best shown in dotted lines in Fig. 1, and this roller 47 is borne upon by a cam, 48, that is keyed to the shaft 24. rIhe lower edges of the parts employed to form the feed-box are faced with leather or rubber, as indicated at 7 in the drawings.

Such being the general construction of the machine, the operation is as follows: The material to be compressed into tablets is delivered to the disk 14within the feed-box, and the shaft 24 is started forward, so as to drive the disk in the direction of the arrow shown in connection therewith in Fig. 2, the lower compressingplunger, 39, being at this time held in the position in which it is shown in Fig. 6, so that as the disk revolves beneath the feed-box the material will be delivered to the bore of the bushing 5, and a complete filling ofthe opening above the top of the plunger 39 will be insured. The cam 4l is adjusted so that as the lower end of the plunger 39 reaches a point approximately beneath a point marked c in Fig. 2 it will act to force the said plunger upward to the position in which it is shown in Fig. 5, the vertical throw of the cam being ad- 5o justed so as to regulate the amount of material retained within the aperture of the bushing 5 above lthe plunger 39, all excess of material which is forced outward above the face of the disk 14 being intercepted and held by the outer section, 33, of the feed-box. After passing from engagement with the cam 41, the plunger 39 will drop back to the position in which it is shown inl Fig. S, and just as the plunger38arrivesat'aposition beneaththehammer 45 the cam 43 will permit the hammer to drop, and the upper plunger, 3S, will be forced downward to the position in which itis shown in Fig. S, the material contained within the bore or aperture ofthe bushing 5 being compressed iuto the form of a tablet. Then, as the disk 14 continues its revolution, the plunger 39 will be forced upward by the action of the cam-block 41, and the tablet will be thrown out upon the disk 14, this movement taking place at the time when the plungerSQ is about beneath the point marked d in Fig. 2.

In Fig. 4 I illustrate a construction wherein the use of the hammer 45 is dispensed with, the plungers 3S and 39 being forced together by the action of wheels or rollers 50, that are arranged as clearl y shown in the figure referred to. In Fig. 11 I illustrate a construction wherein the sleeve 13 is provided with several sets or series of plunger supporting arms. Il' the machine is so arranged,it will ofcourse be understood that the cam 48 (ifa hammer is employed) would be differently arranged and timed.

The form of machine illustrated in Fig. 4 is particularly applicable for use in the manu facture of lozenges or other tablets that are made from powders of a sticky or adhesive nature.

In order that the force blow of the hammer 45 may be varied, I arrange a spring, 49, in connection with the lever46, the tension of this spring being adjusted to suit the requirements of the case by means of a screw, 8, that is engaged by an adjusting-nut, 9, the parts being arranged as shown in Fig. 1.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent" 1. Ina tablet-compressing machine, the combination of an aperturcd` disk, a feed-box held in yielding contact with the disk, plungers secured to the disk and registering with the aperture or apertures therein, and means for revolving the disk and plunger-s and for forcing the plungers together, substantially as herein shown and described.
